Abstract: The invention relates to plastics granules composed of foamable particles derived from a star-shaped fundamental solid having at least three sides, these particles being a three-dimensionally domed structure by virtue of the sides having paraboloidal curvature, and the surfaces of paraboloidal curvature being staggered in relation to one another. These granule particles preferably have three sides and at least one gap. The invention also relates to a packaging material obtained by foaming the said plastics granules. This packaging material exhibits an improved flow while having at the same time an improved packaging action (good packaging properties and a high void volume).

Abstract: of the disclosure: Expandable plastics granular material and packaging material produced therefrom The invention relates to a plastics granular material of foamable particles which are derived from a star-shaped basic body with at least three limbs lying in a plane, the particles having at least one orifice. Preferably, these granular material particles are provided with three limbs and each limb is provided with an orifice. Furthermore, the invention has as its subject a packaging material which is obtained by foaming of the said plastics granular material. This packaging material displays a lower bulk density, improved pourability with simultaneously improved packing effect good packaging properties, large void volume).
